IMPROVEMENT IN VENTILATO RS.

Specification forming part of Letters Patent No. 208,554, dated October1, 1878; application filed September 6, 1878.

To all whom 'it may concern:

Be it known that 1, WILLIAM D. YOUNG, of Philadelphia, Philadelphiacounty, Pennsylvania, have invented Improvements in Ventilators, ofwhich the following is a specification:

My invention is a ventilating attachment constructed and adapted to awindow, as fully described hereinafter, so as to facilitate theventilation of the apartment, as well as serve other useful purposes.

In the accompanying drawings, which form part of the specification,Figure 1 is a perspective view of my invention applied to a window. Fig.2 is a section of the ventilating-blind, and Fig. 3 a view showing amodification.

The attachment consists, essentially, of an arm, F, a post, G, and aswinging frame or plate, E. The arm F is provided with suitableattachments for securing it to or upon the sill of a window. Variousdevices may be employed for this purpose; but I have illustrated in thedrawing a flanged blade, 5, which clamps the bead 2 of the window-frame,and adjusting and retaining screws 7 and 9, by which the angle of thearm may be regulated. In order to support the arm in its horizontalposition, it is preferable to use a bracket, J, which may be in the formof a plate, as shown, so as to serve the purposes of a sign-board.

The post G, which is at the outer end of the arm F, may be securedpermanently, or may be adjustable in any suitable manner on the arm, andmay consist of a single bar of metal, or of a metal base, a, supportinga wooden shaft, 1). The upper end of the post is reduced in diameter toform a shoulder, 03, for a metal block or bearing, J having a recess, 6,to receive the journal f, constituting the upper pivot of the frame E,the lower pivot, f, turning in a bearing in the arm I*, or in the footof the post. The opening or hearing in the block J communicates with aslot in the front of the block, of such width as to permit the passageof a reduced portion, '5, of the journal f when the frame E is elevated,thus permitting the frame to be readily attached and removed.

In order to facilitate the construction, each journal may be attached toor form part of a ast-metal corner-piece, K, into which the pieces ofthe frames are set, increased strength being also thus imparted. Theframe E may be divided into two divisions, c c, the former being closed,and constituting a sign-board, and the latter being provided with slatsor blinds. The action of the wind will carry the frame or plate E in thedirection in which the wind is blowing until it is arrested by strikingthe side of the window-frame, when its inclined position will serve todeflect the current of air inward into the room, thus aiding inventilating the apartment. Any suitable devices may be employed forsecuring the plate in its desired positions. Cushions (1 may be securedto the sides of the plate to prevent it from wounding the bead of thewindow. The post Gr may be provided with a staple, h, to which a cordmay be attached and extended to the window-frame, or a spring may beattached to the post, so as to strike the blind when it assumes thedesired angle, and there hold it. An ordinary Venetian blind may beplaced within the division 0, or may occupy the whole of the frame E. Iprefer, however, to use a series of slats, M, as shown in the drawing.

The end piece, a, of the frame, Fig. 2, has openings for the journals 8of the slats M, and the cross-piece n has similar openings, and isprovided with a vertical groove, 0, and with cross-grooves t. Each slatis equal in length to the space between the uprights, and the journalsare of such length that the slat may be slid outward, and then turnedeither to a horizontal or upright position. To secure the slat whenupright, it is slid back into the groove 0, and to retain it whenhorizontal it is carried into the cross-groove t. After adjustment it issecured by turning down a pendent plate, 10, which prevents the outwardmovement of the journal 8. By this means any one or more of the slatsmay be adjusted.

If desired, the upper trunnion or journal of the frame may be locked tothe block J by a pin or projection on the journal, adapted to a slot inthe block, somewhat in the manner of a bayonet-joint. I do not limitmyself, however, to any special mode of connection.

In some instances the frame may be supported by a post, G, pendent fromthe frame of an awning, and supported by a lighter arm,

F, as shown in Fig. 3; or the journals of the frame may turn in bearingsin the window frame and sash.

In order to collect the air, flanges may be arranged at y, as shown, andcatches u may be secured to the arm f, for holding the usual shutterswhen bowed.

I claim- 1. A ventilating device consisting of an arm, F, adapted forattachment at the window-sill, the post G, supported centrally by saidarm opposite the window, and swinging frame or plate E, supported by thearm and post, substantially as specified.

2. The frame E, provided with journals ff, adapted to hearings in thearm F, and post Gr, arranged centrally opposite the window, as setforth.
